PRl N T lNG PROCESS.

SPECIFICATION forming part of Letters Patent Net 16,087, dated December3, 1903.

Application filed May 19, 1900. $erial No. 17,312. (No specimens.)

T at whom it may concern: Be.-it known that I, ADOLF HOZ, manufacturer,a citizen of Switzerland, residing at Rorschach, Switzerland, haveinvented certain new and useful Improvements in Printing Processes; andIdo herebydeclare the fol,- lowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

and inefiaceable design is formed on such materials by the printingoperation alone and Without the aid of subsequent fixing or mor--danting steps or treatments except the usual steaming in the case ofprinting on textile,

the object being, moreover, to introduce considerable economy into thisart and to enable thesame printing surfaces or roller to be 'used insuccession for printing any number of different designs, thus-making asmall 2 5 stock of surfaces or rollers to answer the demands of a largeprinting establishment. With these objects in view my invention involvesthe combination of fplanographic with chemical printing-that is-to'say,".under ,"f said invention 1 print the design: onthes textile orwallpaper material in such a waythat the design is not only printed onsuch fabric in the manner known as lithographic printing, but is also'inthe sameprinting operation developed and fixed ormordanted orprepared tobe developed and fixed or mordanted V on the said fabric in such a wayas to be permanent and ineffaceablei; This I effect by preparing anysmooth surface of metal or 40 material suitable for planographicprinting with the desired design in such a manner as toadapt it forlithographic printing and then successively damping and inking the samewith an ink containing,besides the dye or em ployed forlithographic inksor crayons, a

V mordant, by which terrnI intend to cover color and .usualfor suitablegreasy ingredients any reagent or substance whereby the dye or color isfixed or developed and fixed on the textile-fabric or paperfl both fllfi terms are included under the general designation ffabric. p

Heretofore lithographic printing from rollershaving a lithographicsurface of stone or suitable metal, such as zinc, has been well known;It has also been proposed to employ engraved, or relief rollers ofaluminium or nickel for the purpose of'printingin the usual way onfabricswith colors or dyes. I, however, am the first to propose and tocarry into successful operation a process whereby the.

lithographic process can becombined in one operation with the process ofprinting fabrics with colors containing the necessary mordants or fixingagents, whereby the design printed thereon will be made permanent andineffaceableafter the usual steaming operation, as is necessary in theart of'calico-printing and allied arts. This is entirely the result of.my discovery.

In carrying out my process I take a smooth roller of suitable metaladapted for lithographing, preferably aluminium or an alloy thereof, andprovide the same with a design insuch a manner as to print therefrom inthe usual-manner of lithograpic or planographic printing, asvis wellknown. I prefer to proceed as followsfl firstprepare the design on atransfer-sheet by printing or otherwise marking the same thereon withlithographic .ink or crayon-that is to say, with an ink containing alarge quantity of grease. The

transfer-sheet for this purpose may be specially prepared paper usuallyemployed in this connection or a gelatin sheet, zinc-foil anindia-rubber sheet,- or the like. After the transfersheet has beensuitably stretched on a flat plate the metal roller is passed or rolledover the same with sufficient pressure to take up the design perfectly.This design is then. fiXBdon the roller, and thelatter is preparedaccording to the nsu al methods employed in: I

lithograph-yer planographic printingthat.

is to say, so that the design portion of its surface willrepel moistureand take up greas'y :iin-k, while the remaining portions thereofwillabsorb-moisture and repelthe ink.- To print from such; a-rollerunder myinvention, the 7 sarneis alternately 'da rnpedand inked with the are91*9 19? which maybe in solid form or in solution, grease in suitablequantity, such as employed for lithographic purposes, and the necessarymordant or fixing agents for fixing or developing and fixing the dye orcolor on the fabric to be printed. It is the latter step whichdistinguishes my invention from all former printing methods, since I amthe first to have recognized and discovered that the lithographic andcolor-fixing agents can be combined and employed on such printing-sirrfaces so as to carry out the planographic printing process and fix ormordant the color or prepare for the fixing or mordanting processes atone operation.

In all fabric-printing, and particularly in printing on cotton-such, forexample, as calico-printingseveral operations have with out exceptionbeen required for preparing and finishing the printed products, whileunder my process the design is printed in such a manner that the dye isfixed or developed and fixed and the greasy medium evaporated all in oneoperation. In addition my process enables me to print calicos andfabrics and mordant or fix the colors from plain or smooth rollers,whereas formerly such operations have been invariably carried out withengraved or relief rollers. This enables me to use the same roller overand over again for a great variety of designs, besides saving the costof engraving. I am thus enabled to reduce my stock of rollers to a verysmall quantity and to cheapen the cost of the individual rollers.Moreover, my process enables me to introduce into the lithographic artthe luminous and brilliant colors or. dyes hitherto employed only intextile printing and dyein g and compared with which the lithographicinks heretofore employed appear dull and faded and insipid. My colors orinks are, moreover, much cheaper than the lithographic inks usuallyemployed, and, moreover, they require only one subsequent treatment intextile printingviz. steaming-whereas the former methods of textileprinting necessitated several treatments before and after printing.

In the accompanying drawings I have represented an example of a machineon which my process can be carried out.

In the drawings, Figure 1 represents a diagrammaticrepresentation,inverticalsectional elevation, of a calico-printing machine resembling inprinciple the well-known calicoprinting machines; and Fig. 2 alongitudinal central section, and Fig. 3 a transverse section, of one ofthe printing-rollers employed in such machine under my invention.

From Fig. 1 it will be observed that a machine on which my process maybe carried out comprises the usual bed or platen roller 5, over whichthe fabric to be printed is fed, the printingrollers 6, 7, and 8, whichare inked by the usual inkingtrains 15 18 1.9 20 22, and ink fonts 30.The printing-machine in the present instance is, however, distinguishedfrom the forms of calico-printing machines hitherto employed by the factthat the printing-rollers 6, 7, and 8 are smoothsurfaced lithographicrollers and that each of them is provided with dampingrollers, such asemployed in lithographic printing. The printing-rollers 6, 7, and 8, asshown in Figs. 2 and 3, consist of smooth seamless metal tubes at, of ametal suitable for lithographing, but which will not be attacked by thechemical materials employed for mordanting or fixing the dyes. For thispurpose I have found aluminium or its alloys particularly valuable.These metal tubes may be mounted on the shaft 1) in any suitable way-e.g., by means of the metal disks or spiders a, a which may be of copperor the like.

While I have herein referred to the use of printing-rollers of aluminiumor aluminium alloy, I do not here claim the same specifically, sincesuch rollers constitute the subjectmatter of my application for LettersPatent, Serial No. 43,522, filed January 8, 1901.

What I claim, and desire to secure by Letters Patent, is

1. The process of printing which consists in preparing a lithographicdesign on a smooth surface then damping and inking the same with an inkcontaining grease and a mordant, and then printing.

2. The process of printing which consists in preparing a lithographicdesign on a smooth roller of material adapted for planographic printing,then damping and inking the same with an ink containing, besides the dyeor color, grease and a mordant medium, and printing therefrom.

3. The process of printing endless fabrics which consists in preparing alithographic design on a smooth roller of metal adapted for lithographicprinting, then damping and inking the same with an ink containing,besides the dye or color, grease and a mordant, and printing therefrom.

4. The process of printing fabrics which consistsi'n damping alithographically-prepared roller of metal adapted for lithographicprinting with an ink containing, besides the dye or color, grease and amordaut, and printing therefrom.

5. The process of printing fabrics which consists in transferring adesign in fatty ink to a smooth roller of metal adapted for lithographicprinting, then preparing said roller for lithographic printing, thendamping and inking the said roller with an ink containing, besides thedye or color, grease and a mordant.

6. The process of printing fabrics, which consists in preparing alithographic design on a smooth surface, then damping and inking thesame with an ink containing a liquid dye combined with grease and amordant, and printing therefrom.

7. The process of printing fabrics, which consists in damping alithographically-prepared roller, then inking the same with an inkcontaining a liquid dye combined with .printing the fabric with saidsurface, then steaming the said fabric.

9. The process of printing fabrics, which consists in damping alithographicaliy-prepared surface, then inking the same with an inkcontaining a liquid dye combined with grease and a mordant, thenprinting thefabric from said surface, and, finally, steaming I 5 thefabric.

In testimony whereof I aflix my signature in presence of two witnesses.
